FIG. 5 is a diagram illustrating an operation procedure of an electronic device according to various embodiments of the present invention, and FIG. 6 is a diagram illustrating fingerprint recognition in an electronic device according to various embodiments of the present invention.

5 and 6, according to an embodiment of the present invention, when a user executes a service requiring personal authentication, the electronic device (for example, the electronic device 101 of FIG. 1) A fingerprint input may be requested.

As the user enters the fingerprint, in operation 501, the electronic device can receive the fingerprint detected by sensing the fingerprint of the user through at least one sensor located in the one area. 6, the electronic device extracts the direction component information 601 by analyzing the input fingerprint (e.g., a fingerprint image), binarizes the extracted direction component information 603, and outputs the binarized By fingerprinting (605), the fingerprint corresponding to the directional component information can be shaped to recognize the fingerprint.

In operation 503, the electronic device can extract the registered authentication information. The registered authentication information may be updated authentication information using the registered authentication information or the stored fingerprint information in the fingerprint registration operation.

In operation 505, the electronic device may detect fingerprint information to be authenticated in the recognized fingerprint image, i.e., detect the feature points, as shown in FIG. 7 attached. The feature points detected in the fingerprint image 701 include, for example, an end point 703 as a point at which a ridge breaks, a bifurcation point 705 as a point at which a ridge breaks, a center point 707 as a point at which a bend is upward or downward, And a delta 709 in which the ridge flow of the fingerprint is gathered in three directions.

In addition, the electronic device may compare (803) the fingerprint information detected in the recognized fingerprint image 801 with the authentication information of the registered fingerprint image 803, as shown in FIG. 8 attached hereto. According to various embodiments, the electronic device can determine the similarity by comparing the positions of the minutiae points of two fingerprint images. If the input fingerprint is a fingerprint of the same person, that is, authentication succeeds . The degree of similarity may be determined using the matching score indicating the matching number of the minutiae, the position of the minutiae points, or the matching degree of the fingerprint image shape.

In operation 507, the electronic device can confirm whether authentication of the input fingerprint is successful based on the comparison result of the fingerprint information of the input fingerprint and the extracted authentication information. The electronic device can determine that the authentication is successful if the similarity is not included within a predetermined range (authentication rejection range) according to the authentication success rate and the failure rate.

If it is determined that the fingerprint authentication is successful, the operation 509 is performed. If the fingerprint authentication fails, the user can proceed to the operation 501 to receive a new fingerprint.

In operation 509, the fingerprint information detected in the input fingerprint (for example, the fingerprint image or the position and type of the feature point of the fingerprint image) may be stored in the fingerprint information database as authentication of the fingerprint inputted by the electronic device is successful.

In operation 511, the electronic device can check whether a specific event for confirming a change in the fingerprint over time has occurred. The specific event for confirming the change of the fingerprint according to the passage of time is that when a certain number or more of pieces of fingerprint information accumulated in the fingerprint information database are stored and when new fingerprint information is stored in the fingerprint information database, When the feature points analyzed in the partial fingerprint area of the registered finger of the registered finger or in the fingerprint area as the wound area are not mismatched or detected a predetermined number of times or the similarity of the fingerprint information stored most recently is within the set range, , At least one of season, temperature, humidity, set time, and set period). In addition, the controller 210 performs an operation for confirming a change according to the authentication time of the fingerprint using all or part of the fingerprint information stored in the fingerprint information database, or uses the stored fingerprint information for a set time interval So as to perform an operation for confirming a change according to the authentication time of the fingerprint.

If it is determined in operation 511 that no specific event has occurred, the electronic device may perform the operation 501 again.

As a result of checking in operation 511, when a specific event occurs, the electronic device can generate authentication information based on the similarity information stored in association with the authenticated time in the fingerprint information database. The electronic device checks the stored similarity information (e.g., matching score, similarity rate, or minutia location) corresponding to the fingerprint information stored in the fingerprint information database, and determines whether the determined similarity information is less than a threshold If it is within the critical range, new authentication information can be generated based on the selected fingerprint information. The selected fingerprint information includes, for example, information stored most recently, at least one fingerprint information stored for a predetermined time, fingerprint information corresponding to the lowest similarity information stored for a predetermined time, or similarity information having a high frequency for a predetermined time The fingerprint information may be at least one of a plurality of pieces of fingerprint information.

According to various embodiments, the electronic device identifies similarity information for authenticated fingerprints, and determines that there is a change in the fingerprint of the same person if the similarity information contained in the fingerprint is lower than a predetermined threshold or within the critical range can do. The threshold value or the threshold value range may be set to a value (for example, similarity rate: 45%) set higher than the lowest similarity information for which the lowest authentication can succeed or a certain range (for example, similarity rate: 45% To 50%). For example, as shown in Table 1 below, if the threshold value is set to 45%, the similarity information of 43% lower than the threshold value is detected, and the authenticated # the fingerprint for the fingerprint information is changed in a large amount compared with the fingerprint registered, so that the authentication information for updating the registered authentication information using the #n fingerprint information can be generated.

In addition, according to various embodiments, the electronic device detects at least one similarity degree information showing an abrupt difference between the authenticated fingerprints and the authentication information to update the registered authentication information based on the detected similarity degree information Can be generated. For example, as shown in Table 1 below, the similarity information (43%) of the #n fingerprint information of the tn authentication time is compared with the similarity information (50%) of the # n-1 fingerprint information of the tn- Since there is a sudden difference of 10% or more, the change in the fingerprint is larger than the fingerprint in which the fingerprint for the #n fingerprint information is registered, so that new authentication information can be generated using the #n fingerprint information.

In addition, according to various embodiments, the electronic device may detect a similarity degree information of a certain range, similarity degree information having a frequent number of times or a lowest similarity degree information among the similarity information stored therein, fingerprint information corresponding to the detected similarity degree information So that new authentication information can be generated. For example, in the following Table 1, the similarity information (50%) of tn-1 having the lowest similarity information in the interval from t4 to tn-1 is detected and the fingerprint information of tn-1 corresponding to the detected similarity information So that new authentication information can be generated.

time t1 t2 t3 t4 ... tn-1 tn Fingerprint information  # 1 fingerprint information # 2 Fingerprint information # 3 Fingerprint information # 4 Fingerprint information ... # n-1 Fingerprint information #n fingerprint information Similarity rate  98% 80% 85% 75% ... 50% 43%

In operation 515, the electronic device can update the authentication information registered with the generated authentication information.

Also, according to various embodiments, the controller 210 may generate authentication information using at least one fingerprint information stored every time the specific event occurs, and may update the authentication information registered with the generated authentication information .

In addition, according to various embodiments, the electronic device may detect a plurality of redundant minutiae among the minutiae included in the stored fingerprint information and generate authentication information to be updated based on the detected minutiae (e.g., fingerprint image, The position or kind of the minutiae point). The generated authentication information may be configured to form a shape of a fingerprint image based on the detected minutiae points or to synthesize fingerprint images based on the accumulated fingerprint information.

In addition, according to various embodiments, the electronic device generates a fingerprint image using the feature points having a lot of accumulation in time based on the location information of the feature points with respect to the fingerprint information, analyzes the generated fingerprint image and the fingerprint image It is possible to configure authentication information including one piece of information. In addition, according to various embodiments, the electronic device uses the location information of the minutiae points to identify the location change direction of the minutiae points with time, and generates the authentication information to be updated using the minutiae acquired based on the confirmed change direction .

In addition, according to various embodiments of the present invention, when the authentication result fails to be continuously consecutively out of the authentication range, but the authentication result falls within the threshold level of the set rejection, It is possible to identify whether the degree of similarity is low only in a specific region by comparing the degree of similarity with the authentication information for each region. If the degree of similarity is low only in the specific area, the electronic device can determine that the fingerprint authentication is successful. According to various embodiments, the electronic device may configure authentication information to be updated with minutiae in the remaining area except the minutiae in the area of low similarity to the fingerprints stored in the fingerprint information database. Also, the electronic device acquires reference feature points in the fingerprint areas with high similarity, generates a fingerprint image based on the acquired reference feature points, and updates the generated fingerprint image or the generated fingerprint image using the fingerprint information analyzed Authentication information can be generated.

The electronic device may, for example, analyze the statistical information and set a shorter period for updating the registered authentication information when it is determined that the rate of change of the fingerprint is high in a high humidity season. On the other hand, The period for updating the authentication information can be set longer.

Further, according to various embodiments of the present invention, the electronic device may be configured to provide fingerprint information for fingerprints that have been successfully authenticated to a user (e.g., at least one of the time, day, week, month, year, Can be managed separately.

According to the fingerprint authentication operation procedure according to the various embodiments of the present invention as described above, the electronic device can be configured to generate statistical graphs based on the fingerprint authentication result when providing the service according to the user authentication, can do. The statistical graphs may indicate a false rejection rate (FRR) 901 and a false acceptance rate (FAR) 903, The same error rate (EER) 905 and the same error rate 905 can be expressed as thresholds for fingerprint authentication. The electronic device can statistically process the FRR, the FAR, and the EER by accumulating the result of authenticating the recognized fingerprint every time the fingerprint is recognized and authentication is performed. Further, the electronic device can update the registered authentication information by using the similarity information of the fingerprint that has succeeded in fingerprint authentication, thereby increasing the fingerprint authentication success rate. Accordingly, as shown in FIG. 10, the first statistical graph 1001 (for example, a true match statistic graph) 1001 may be moved in a fluid manner with time to lower the EER 1003, The threshold level, that is, the rate of accepting others (1005) may be lowered.
